My V8 1969 Mustang is in need of new rear brake slave cylinders. On the ones on my car, the brake line screws into the slave cylinder straight and on and the ones I am looking on line the inlet is on a slight angle. I have been looking on line and it appears there are two different types and the ones I have on my Mustang are for a 6cylinder car. My car has Falcon XY to XF ventilated front discs with PBR Calipers. It is an original V8 car and has the V8 diff. Do I need the angled slave cylinders (It won't be a problem putting a slight bend in the brake line), or do I stick with the ones with the inlet that goes in straight below the bleed nipple. Any advice is greatly appreciated. Cheers Coops
